 When the postbox_classes() function returns an empty  string, we have an
 unnecessary space after postbox.

 {{{
 <div id="submitdiv" class="postbox " >
 }}}

 {{{
 <div id="formatdiv" class="postbox " >
 }}}


 {{{
 <div id="postimagediv" class="postbox " >
 }}}

 This patch gives no unnecessary space when postbox_classes returns an
 empty string.
